CENTRAMATIC balancers all around. (BALANCE MASTER nicer yet). Quite common now in Class 8. My 579 Pete has them at every position. The shop at Alvarado, TX is great to deal with. (And my 35’ Silver Streak is so equipped).
Have a look at STENGEL BROTHRS “Wheel Centering Tools”. Even if you have to buy your own, reducing Vibration is worth every effort. Research as a topic in big truck resources.
With whatever you all have been using in MOHO-land to keep duals at same pressure, such as CROSSFIRE.
I’d imagine Roger Marble has ideas.
